The Macintosh TV uses a 2× SCSI caddy-loading CD-ROM drive. Apple CD-ROM caddies are model-specific.

== ⚠️ Recap and PRAM battery ==

The Macintosh TV is built on an LC-series logic board and uses '''surface-mount electrolytic capacitors that leak''' with age, corroding the board — recap and clean it as a first step. It also carries a lithium '''PRAM battery''' that leaks/bursts; remove it from any un-serviced unit and clean any corrosion.<ref name="cc_batt">[https://68kmla.org/bb/threads/warning-exploding-maxell-pram-batteries.25169/ 68kMLA — exploding Maxell PRAM batteries].

== All-in-one analog board ==

As an all-in-one with a built-in CRT, the Macintosh TV has an analog board like the compact and Color Classic Macs. '''No video with a chime''', a collapsed raster, vertical lines, dim or distorted video point to the analog board — reflow cracked solder joints (deflection yoke and flyback) and recap the analog board. It is based on the LC 520 and adds a TV tuner; if the computer works but the TV function does not, check the tuner card and its input before the main logic.<ref name="cc_cap">[https://recapamac.com.au/ Recap-a-Mac] and 68kMLA recap threads.
